## redis 5.0集群部署步骤 ## 1. 下载源码编译 ``` # wget http://download.redis.io/releases/redis-5.0.0.tar.gz # tar xzf redis-5.0.0.tar.gz # cd redis-5.0.0/ # make ``` 编译源码报以下失败信息 ``` cc: error: ../deps/hiredis/libhiredis.a: No such file or directory cc: error: ../deps/lua/src/liblua.a: No such file or directory cc: error: ../deps/jemalloc/lib/libjemalloc.a: No such file or directory ``` 先进入deps目录编译依赖库 ``` # cd deps/ # make hiredis jemalloc linenoise lua # cd .. # make ``` 编译成功 ## 2. 创建六个集群的配置文件 ``` # mkdir cluster && cd cluster # mkdir 7001 7002 7003 7004 7005 7006 ``` 分别将项目根目录的redis.conf的配置文件复制到上面六个目录下。修改配置文件以下内容(其中 port 和 pidfile 需要随着文件夹的不同调增)： ``` port 7001 #端口 # bind 127.0.0.1 cluster-enabled yes #启用集群模式 cluster-config-file nodes-7001.conf cluster-node-timeout 5000 #超时时间 appendonly yes daemonize yes #后台运行 protected-mode no #非保护模式 pidfile /var/run/redis_7001.pid ``` ## 3. 启动节点 ``` ./src/redis-server cluster/7001/redis.conf ./src/redis-server cluster/7002/redis.conf ./src/redis-server cluster/7003/redis.conf ./src/redis-server cluster/7004/redis.conf ./src/redis-server cluster/7005/redis.conf ./src/redis-server cluster/7006/redis.conf ``` ## 启动集群 ``` ./src/redis-cli --cluster create 192.168.4.64:7001 192.168.4.64:7002 192.168.4.64:7003 192.168.4.64:7004 192.168.4.64:7005 192.168.4.64:7006 --cluster-replicas 1 ``` 输出： ``` >>> Performing hash slots allocation on 6 nodes...
